Three ways to log,
zero data shared

Type it, speak it, or snap it. Every transaction is understood locally by an on-device model — no servers, no tracking, no account required.

[0003] · voice

Speak your spend

"Twelve bucks on lunch." Hold the mic, speak naturally, release. Transcribed and parsed on-device.

[0004] · receipts

Snap a receipt

Point, shoot, done. The on-device vision model pulls out vendor, date, and total — never uploaded anywhere.

[0005] · tap to pay

Works with Apple Pay

Every tap at checkout logs itself. Digits listens for Apple Pay confirmations and files the transaction before your card even leaves your wallet.
